A novel standardized moment invariants is presented in order to extract image feature of vehicle face during the process of vehicle model classification and identification. Based on the process of auto-face segmenting,interested region extracting,and the shape contour obtaining by contour tracing technique,the traditional HU moment invariants are normalized,which is in comparison with typical HU moment invariants. Experimental results demonstrate that much higher accuracy in terms of feature vector can be achieved by the introduced model.
